Jet is a standard dark gray stone found in large clusters in sedimentary layers.
In real life, jet is actually derived from decaying wood under extreme pressure and is an extremely low grade of lignite. However, jet is useless as a fuel, although historically it has been a popular source of jewelry and crafts.
